According to the brown coal drying machine, the shafts and the spiral heat transfer pieces make direct contact with brown coal in a heat tracing mode, heat carriers directly enter machine body jackets and the rotating hollow shafts, the heat transfer area per unit volume is large, and heat efficiency is high.
Description
Technical field
The present invention relates to a kind of brown coal drying machine.
Background technology
Brown coal are a kind of brownish black, lacklustre grizzles between peat and pitch coal, are characterized in that water content is large, fugitive constituent is high, burning-point low (120 ℃～160 ℃).
Brown coal are the same with other coal source, and exploitation out all will be passed through washing, selects the brown coal of high-quality, and the accessory substance of washing is not easy to utilize equally later.Effective method is by coal slime dewatering, utilizes coal slurry drying-machine, brown coal dryer by the wet coal slime dewatering drying of raw material, improves efficiency of combustion, and coal resources are utilized more fully.Yet brown coal drying machine in the market can not reach desirable drying effect, all exists output few, dry and do, fluctuation of service, the problem of easily catching fire or exploding.
Summary of the invention
For overcoming the defect of prior art, the object of the present invention is to provide a kind of improved brown coal drying machine.
For realizing above-mentioned target, the present invention adopts following technical scheme: the brown coal drying machine comprises one-level drier host machine and secondary drying machine host, axle is housed respectively on the firsts and seconds drier host machine, spiral heat transfer sheet for conducting heat and carrying is housed on axle, on the firsts and seconds drier host machine, be respectively equipped with charging aperture and discharging opening, the discharging opening on the one-level drier host machine is connected with the charging aperture on the secondary drying machine host.
Brown coal drying facility of the present invention have following beneficial effect:
1. occupation area of equipment is little, energy consumption is low
2. separate unit maximum throughput: be 30 to ram the loose soil with a stone-roller after sowing/h (exceeding three times than the efficiency of other drying equipments)
3. spontaneous combustion-control temperature
Dust few-intercept explosion phenomenon
5. handling good
6. complete equipment and technology arrangement are simple
The accompanying drawing explanation
Fig. 1 is the schematic diagram of brown coal drying machine of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
As shown in Figure 1, brown coal drying machine of the present invention comprises one-level drier host machine 10 and secondary drying machine host 20.Each drier host machine is comprised of critical pieces such as housing, top cover, end caps, and housing comprises inner bag, chuck, insulation in housing, top cover adopt, and cylinder lining and top cover, according to the difference of dried material, adopt different inner lining material and anti-corrosion measure.
On one-level drier host machine 10 and secondary drying machine host 20, axle 30 is housed respectively, axle 30 passes one-level drier host machine 10 and secondary drying machine host 20, on axle 30, is positioned on the part of drier host machine 10,20 spiral heat transfer sheet 31 is housed.Spiral heat transfer sheet 31 is welded on axle 30, and its effect is conduct heat and carry.One end of axle 30 supports by bearing block 40, and the other end drives rotation by motor 50 by reduction gearing mechanism, and transmission mechanism adopts frequency control to control the material handling amount.
On one-level drier host machine 10 and secondary drying machine host 20, be respectively equipped with charging aperture 60, discharging opening 70, weep hole 80, steam inlet 91, and condensation-water drain 92.The discharging opening 70 of one-level drier host machine 10 is connected with the charging aperture 60 of secondary drying machine host 20.Charging is delivered to brown coal drying machine entrance by batcher by material, takes out the humid air in body because drying equipment needs blower fan, and charging aperture needs good sealing.Discharging opening 70 connects conveying worm dry complete brown coal is sent.Steam enters in minute drum by main steam range (its flow can be controlled by flowmeter), is separated by a minute drum, passes into respectively in the axle of drying machines at different levels and flight, interlayer, and steam condensate is discharged by steam trap connection.The steam pipework of turnover drying machine must be by chuck steam inlet pipe, sharf steam inlet pipe separately, and every steam inlet pipe must fill the throttle flow size that control valve is controlled each pipeline; The corresponding independent configuration of the drain valve of outlet pipe end and steam inlet pipe, the independent drain valve of outlet water at tail end mouth configuration of each admission pipeline.Heating steam pressure is 0.4～0.5MPa, temperature while being 180 ℃-210 ℃, must guarantee that bearing strength and the brown coal of drying equipment do not catch fire in drying equipment, and explosion-proof safety devices should be arranged.
Heat carrier directly passes in the spiral heat transfer sheet 31 of rotation, and brown coal add in one-level drier host machine 10 and secondary drying machine host 20 continuously from charging aperture 60, are delivered to discharging opening 70 and are discharged outside machine by spiral heat transfer sheet 31.Material is in heat exchange, course of conveying, through spiral heat transfer sheet 31, constantly stir, brown coal are in the on dry run that completes always, brown coal are contacted with body spiral heat transfer sheet 31 fully, enter the brown coal of drying machine through bringing-up section, brown coal, from normal temperature to this process of water evaporating temperature, complete in a short period of time, the temperature of axle 30 and spiral heating sheet 31 must keep enough steam pressures always, so just can the thermal efficiency be mentioned the highest.
